THOMAS V. PLICE, OF ASHLAND, OHIO, ASSIGNOR TO W. V. B. TOPPING, FASI-ILAND,

' OHIO.-

DOOR-SUPPOR'IIN'G STRUCTURE.

To all whom it may concern: I

Be it known that I, THOMAS V. PLICE, a

, citizen of the United States, resident of Ashland, county of Ashland,and State of Ohio, have invented a new and useful Improvement inDoor-Supporting Structures, of which the following is a specification,the principle of the invention being herein ex plained and the best modein which I have contemplated applying that principle, so as todistinguish it from other lnventions.

My invention relates to door-supporting structures, and particularly tothat class of door supports used in connection with sliding doors. I

The object of the invention is to provide a track and supportingbrackets therefor which will be economical in construction and efficientin operation and use.

The said invention relates particularly to that class of door supportsin which is used the tubular form of track, such as is shown, describedand claimed in application of Edward W. Topping, filed August 12, 1909,bearing Serial No. 512,585.

The said invention consists of means hereinafter fully described andparticularly set forth in the claims.

The annexed drawing and the following description set forth in detailcertain means embodying my invention, the disclosed means, however,constituting but one of various mechanical forms in which the principleof the invention may be applied.

In said annexed drawing: Figure 1 represents a front elevation of abracket and a section of track embodying my invention. Fig. 2 representsa cross-section of the track and support, together with the endelevation of one of the brackets secured to such support and supportingthe track. Fig. 3 is a fragmentary perspective view of the complementarysupporting member forming one element of the bracket. Fig. 4 representsa front elevation of a modified form of bracket and a section of trackembodying my invention. Fig. 5 represents a crosssection of the trackand support, together with an end elevation of the modified form oftrack. Fig. 6 is a fragmentary perspective view of the complementarysupporting member of the modified form.

While the illustrated form of the invention is shown as particularlyadapted for use in connection with the form of track Specification ofLetters Patent.

Application filed May 12, 1910.

Patented May 16, 1911.

Serial No. 560,870.

above mentioned, it will be understood that the principle of saidinvention may be applied to any tubular track in which the runways arelocated upon the interior.

The structure involving my invention as illustrated by Figs. 1, 2 and 3of the drawing, consists of the tubular track A provided with theinterior runways a a, which are upwardly curved, as shown, and terminateon the inside with the downwardly projecting flanges a a. This track issupported by a plurality of brackets, each of which is secured to themain support or building B by means of suitable screws or bolts G. Eachbracket comprises in its structure a main supporting member D, acomplementary supporting member D, and a fastening device D which inthis case consists of a bolt d and nut d. The supporting member D isformed with an upper extension d which is placed directly against thesupport 13, and which is provided with a suitable bolt-hole throughwhich the bolt or screw C passes. The lower end portion of of member Dis curved so as to form an interior concave surface, whose contourconforms with the outer side of the track A, and which is thereforeadapted to receive such surface of said track. The upper inside portionof the lower extremity of the member D is provided with a lug cZ whichprojects some distance beyond the longitudinal upper center line of thetrack, so that the interior surface of said extremity surrounds morethan one-half of the periphery of the track. Intermediately of theextension (Z and the lower end portion d of the bracket is an inclinedportion 61 which is formed with a bolt-hole about midway its length.Against the inner surface of this intermediate portion is seated theupper extremity d of the complementary supporting member D. The main orlower portion of this complementary member is formed inside with asurface corresponding in its contour with the remaining unsurroundedportion. 7

of the tracks periphery, as shown in Fig. 2,

so that the two members D and D together when the complementary member Dis drawn into the angle formed by the intermediate portion d and the lug(Z when the track is in place, a binding action will be exerted upon thelatter. The two members D and D are held together by means of the bolt(Z and nut d. That portion of the bolt immediately beneath its head ispreferably squared, and passes through a square hole (Z formed in theangular portion (Z of the member D, this arrangement permitting the boltto be held fast while the nut d is screwed thereon, as will be readilyunderstood.

By means of the above construct-ion, it will be seen that by looseningthe nut d, the bracket may be loosened and the track slid along therein,so that a proper adjustment of such track in the brackets may be readilyobtained, after which the nuts are securely tightened on the bolt, thebracket thereby clamped upon the track, and the latter securely heldtherein. It will be noted that the nuts (Z may be moved a considerabledistance on the fastening bolts, and the member D loosened to such anextent that the track may be practically disengaged from the bracketswhile being adjusted in place. These tracks being ordinarily japanned,such adjustment may be effected Without marring or injuring the japannedsurface thereof. The form of the tubular track is such that it may betilted upon the extremity d of the lower end (Z of member D as an axis,without being intercepted by the lug d*, as is indicated by the radiusand are of the circle shown in Fig. 2.

Referring now to the modification illustrated by Figs. 4, 5 and 6, thecomplementary member D is arranged to surround the outside of the trackA, the main member D being secured as before to the support B, extendinginwardly surrounding the inner part of the track and fastened below thelatter by means of a screw C to said support. The intermediate portion615 of the main member is upright and slightly inclined outwardly, asshown, and the complementary member D is provided with an upper andinwardly projecting portion (Z which rests upon the top of saidintermediate portion. In this case the main member D is provided with asquared opening 6V, and angular bosses (Z and al are provided on theinside of the main member and outside of the complementary memberrespectively, whose outer faces are substantially perpendicular when thebracket is in its normal clamping position, the intermediate portion (Zand end portion d of the complementary member D being slightly inclinedwhen in this normal position, as will be read ily understood from aninspection of the drawing.

Having fully described my invention, what I claim and desire to secureby Letters Patent is 1. In a door-supporting structure, the combinationwith a tubular track; of a bracket comprising in its structure a mainsupporting member engaging one side of said track, and a complementarysupporting member engaging the opposite side of said track andadjust-ably secured to said main member.

2. In a doorsupporting structure, the combination with a tubular track;of a bracket comprising in its structure a main supporting memberengaging the outer side of said track, a complementary supporting memberengaging the opposite side of said track, and adapted to be supportedthereby, and adjusting means including a screw for securing said twomembers to each other, whereby said bracket may be loosened and arelative movement of track and bracket permitted in the longitudinaldirection of the track.

Signed by me, this 20th day of April, 1910.

THOMAS V. PLIGE.
